Final answer:
The greenhouse effect and the current carbon cycle are contributing to global warming. To reduce CO2 emissions, you can reduce energy consumption and promote renewable energy sources.
Step-by-step explanation:
The greenhouse effect and the current carbon cycle with fossil fuels are both affecting the Earth's climate. The greenhouse effect is causing a rise in Earth's temperature, known as global warming or global climate change. The emission of greenhouse gases from burning fossil fuels contributes to this effect, as these gases trap heat in the atmosphere.
To reduce the amount of CO2 emissions, one activity you can do is to reduce your energy consumption. This can be achieved by using energy-efficient appliances, turning off lights and electronics when not in use, and using public transportation or carpooling instead of driving alone. Additionally, you can promote renewable energy sources by installing solar panels or supporting initiatives that advocate for clean energy.
